After examining the briefs and appellate record, this panel has determined
unanimously that oral argument would not materially assist the determination of
this appeal. See Fed. R. App. P. 34(a); 10th Cir. R. 34.1.9. The case is therefore
ordered submitted without oral argument.

This is a pro se 28 U.S.C. § 2255 prisoner appeal. Defendant pleaded
guilty to possession with intent to distribute fifty kilograms or more of marijuana
in violation of 21 U.S.C. § 841(a)(1) and (b)(1)(C). He was sentenced to thirty-three
months' incarceration followed by a three-year term of supervised release.
Defendant did not appeal his conviction or sentence.

In his § 2255 motion, Defendant claimed that his counsel was ineffective
because he failed to inform Defendant that his sentence could be increased
because of his prior convictions. A claim for ineffective assistance of counsel
requires Defendant to show that (1) his attorney's "performance was deficient . . .
[in that he] made errors so serious that counsel was not functioning as the
'counsel' guaranteed by the Sixth Amendment," and (2) "the deficient
performance prejudiced the defense." Strickland v. Washington, 466 U.S. 668,
687 (1984). A court need not address both prongs of the Strickland test "if
[Defendant] fails to make a sufficient showing of one." Cooks v. Ward, 165 F.3d
1283, 1292-93 (10th Cir. 1998). The district court denied Defendant's motion
holding that he failed to demonstrate prejudice as a result of his attorney's
allegedly deficient performance. In addition, the district court denied
Defendant's request for a certificate of appealability.

Defendant has renewed his request for a certificate of appealability with
this court. In order for us to grant this request, Defendant must make a
"substantial showing of the denial of a constitutional right." 28 U.S.C. §
2253(c)(2) (2000). To do so, he must demonstrate "that reasonable jurists could
debate whether (or, for that matter, agree that) the [motion] should have been
resolved in a different manner or that the issues presented were adequate to
deserve encouragement to proceed further." Slack v. McDaniel, 529 U.S. 473,
484 (2000) (quotations omitted).

Defendant's argument on appeal is exactly the same as that raised in the
district court ­ that his attorney was constitutionally infirm because he failed to
advise Defendant that his prior convictions could increase his sentence. The
district court, relying on Laycock v. New Mexico,
880 F.2d 1184, 1187 (10th Cir.
1989), concluded that Defendant
failed to establish prejudice because his
allegations did not demonstrate a reasonable probability that he would have not
pleaded guilty and insisted on going to trial.

We have carefully reviewed the briefs, the district court's disposition, the
record on appeal, and the relevant law. For substantially the same reasons as
articulated by the district court, we agree that Defendant's allegations do not
establish "a reasonable probability that, but for counsel's [alleged] errors, he
would not have pleaded guilty and would have insisted on going to trial."
Laycock, 880 F.2d at 1187. The Slack v. McDaniel standard has not been
met.

We DENY Defendant's request for a certificate of appealability and
DISMISS this appeal.
